Nasal and paranasal sinus carcinoma: are we making progress? A series of 220 patients and a systematic review.

BACKGROUND: The authors reviewed treatment results in patients with nasal and paranasal sinus carcinoma from a large retrospective cohort and conducted a systematic literature review. METHODS: Two hundred twenty patients who were treated between 1975 and 1994 with a minimum follow-up of 4 years were reviewed retrospectively. A systematic review of published articles on patients with malignancies of the nasal and paranasal sinuses during the preceding 40 years was performed. RESULTS: The 5-year survival rate was 40%, and the local control rate was 59%. The 5-year actuarial survival rate was 63%, and the local control rate was 57%. Factors that were associated statistically with a worse prognosis, with results expressed as 5-year actuarial specific survival rates, included the following: 1) histology, with rates of 79% for patients with glandular carcinoma, 78% for patients with adenocarcinoma, 60% for patients with squamous cell carcinoma, and 40% for patients with undifferentiated carcinoma; 2) T classification, with rates of 91%, 64%, 72%, and 49% for patients with T1, T2, T3, and T4 tumors, respectively; 3) localization, with rates of 77% for patients with tumors of the nasal cavity, 62% for patients with tumors of the maxillary sinus, and 48% for patients with tumors of the ethmoid sinus; 4) treatment, with rates of 79% for patients who underwent surgery alone, 66% for patients who were treated with a combination of surgery and radiation, and 57% for patients who were treated exclusively with radiotherapy. Local extension factors that were associated with a worse prognosis included extension to the pterygomaxillary fossa, extension to the frontal and sphenoid sinuses, the erosion of the cribriform plate, and invasion of the dura. In the presence of an intraorbital invasion, enucleation was associated with better survival. In multivariate analysis, tumor histology, extension to the pterygomaxillary fossa, and invasion of the dura remained significant. Systematic review data demonstrated a progressive improvement of results for patients with squamous cell and glandular carcinoma, maxillary and ethmoid sinus primary tumors, and most treatment modalities. CONCLUSIONS: Progress in outcome for patients with nasal and paranasal carcinoma has been made during the last 40 years. These data may be used to make baseline comparisons for evaluating newer treatment strategies.

Combined buccal mucosa island and sternohyoid flaps: a new technique of hemilaryngeal reconstruction studied in a canine model.

No single method of reconstruction has proven ideal for all patients with defects following vertical hemilaryngectomy. In this report, we detail a new technique for hemilaryngeal reconstruction involving the use of a pedicled buccal mucosa island flap supplied by the facial artery and vein. The buccal flap was used to resurface a transversely oriented sternohyoid myofascial flap. The reconstructive outcome was analyzed in 4 animals, 3 of which survived the early postoperative period. Videoendoscopy and stroboscopy were performed to analyze the laryngeal configuration and vibration. Each subject was decannulated and had a competent airway free of aspiration. After sacrifice of the animals, whole organ axial sections were made at multiple levels. Endoscopic and histologic findings documented that this technique produced an appropriate neocord position. Laryngeal stroboscopy in each animal showed bilateral mucosal traveling waves, with entrainment of the reconstructed neocord mucosa and native vocal cord mucosa. We conclude that the layered reconstructive technique described, compared to traditional methods of reconstruction, more closely replicates the structure of the excised tissue in hemilaryngeal reconstruction, potentially resulting in an improved voice outcome.

Radial forearm free flap pharyngoesophageal reconstruction.

OBJECTIVES: This study evaluates the outcome of pharyngoesophageal reconstruction using radial forearm free flaps with regard to primary wound healing, speech, and swallowing in patients requiring laryngopharyngectomy. STUDY DESIGN: Retrospective review in the setting of a tertiary, referral, and academic center. PATIENTS AND METHODS: Twenty patients underwent reconstruction of the pharyngoesophageal segment using fasciocutaneous radial forearm free flaps. RESULTS: All free flap transfers were successful. An oral diet was resumed in 85% of the patients after surgery. Postoperative pharyngocutaneous fistulas occurred in 4 patients (20%) with 3 resolving spontaneously. Distal strictures also occurred in 20% of the patients. Five patients who underwent tracheoesophageal puncture achieved useful speech. CONCLUSIONS: Advantages of radial forearm free flaps for microvascular pharyngoesophageal function include high flap reliability, limited donor site morbidity, larger vascular pedicle caliber, and the ability to achieve good quality tracheoesophageal speech. The swallowing outcome is similar to that achieved after jejunal flap pharyngoesophageal reconstruction. The main disadvantage of this technique relates to a moderately high incidence of pharyngocutaneous fistulas, which contributes to delayed oral intake in affected patients.

The role of hyperplasia in multiple parathyroid adenomas.

BACKGROUND: Parathyroid adenoma is the most common cause of primary hyperparathyroidism (pHPT). Adenomas usually involve only a single gland, and the remaining glands are normal or suppressed. Multiple parathyroid adenomas have been reported to occur in as high as 11% of patients with pHPT. The significant incidence of multiple adenomas with histologic similarities to hyperplasia has raised the possibility that adenoma is a continuation of the hyperplasia state. To test this theory, we used molecular genetics to compare clonality and proliferative activity of parathyroid adenoma with its corresponding normal glandular tissue. Furthermore, we devised a scheme to definitively distinguish between the different parathyroid states on a molecular level, because histologic distinction is unreliable. METHODS: The study included three patients with a diagnosis of singular parathyroid adenoma and three with double parathyroid adenomas. Paraffin-embedded surgical specimens of both adenomas and normal glands were retrieved from each patient. Clonal analysis of the phosphoglycerolkinase (PGK) gene has suggested that parathyroid adenomas are monoclonal. Clonality of parathyroid adenomas and normal parathyroid glands was studied by polymerase chain reaction-based restriction fragment length polymorphic analysis for the PGK gene. Proliferative activity of the specimens was also analyzed using the immunohistochemical markers PCNA and Ki-67. RESULTS: All adenomas were monoclonal and all normal parathyroid glands were polyclonal for the PGK gene in both the single and double adenoma specimens. All adenomas stained positive for proliferative activity. In the three patients with singular adenoma, proliferative activity was not detected in the normal parathyroid tissue. However, in the double adenoma group, two of the three patients showed hyperproliferative activity in the normal glands. CONCLUSION: Proliferative activity consistent with hyperplasia was present in some normal glands of multiple adenoma patients. Our observation supports the theory that multiple adenomas may be a continuation of the hyperplasia state.

Adenoid cystic carcinoma of the base of the tongue.

A retrospective review of 14 patients with adenoid cystic carcinoma of the tongue treated between 1955 and 1997 was performed. Treatment consisted of surgery (n = 2), radiotherapy (n = 2), chemotherapy (n = 1), or combination therapy (n = 9). The 2-, 5-, and 10-year absolute survival rates were 92%, 79%, and 63%, respectively. Seventy-five percent of the patients who died of cancer succumbed to distant metastases. However, long-term survival was common despite a high incidence of local and distant recurrence. The presence of positive surgical margins, the incidence of regional metastases, the incidence of perineural invasion, the initial stage of disease, and the eventual development of locoregional recurrence and distant metastases did not significantly alter the survival rate. Surgical extirpation combined with postoperative radiotherapy is advocated for the treatment of adenoid cystic carcinoma of the tongue. Given the indolent nature of this disease process, surgery should be directed toward conservation of speech and swallowing function.

Esthesioneuroblastoma: a meta-analysis and review.

Our objective was to review recent developments in diagnosis, staging, and treatment of esthesioneuroblastoma (ENB). A meta-analysis of publications between 1990 and 2000 was carried out, and studies were classified according to their main subject: origin/aetiology of ENB, histopathological diagnosis, and treatment. Data so far point to the basal progenitor cells of the olfactory epithelium as the origin of ENB. Histopathological diagnosis remains difficult and is based on results of antigen expression detected through a panel of antibodies by immunohistochemistry. RT-PCR of HASH expression could be a specific marker of ENB. Overall and disease-free survival at 5 years averaged 45% (SD 22) and 41% (SD 21) in the studies included in the meta-analysis. Survival in Hyams' grades I-II was 56% (SD 20) compared with 25% (SD 20) in grades III-IV (odds ratio 6.2). In patients with metastases in cervical lymph nodes (on average 5% of the total) survival was 29%, compared with 64% for patients with N0 disease (odds ratio 5.1). Survival according to treatment modalities was 65% for surgery plus radiotherapy, 51% for radiotherapy and chemotherapy, 48% for surgery, 47% for surgery plus radiotherapy and chemotherapy, and 37% for radiotherapy alone. The histopathological grading according to Hyams and the presence of cervical lymph-node metastases emerged as prognostic factors. A combination of surgery and radiotherapy seems to be the optimum approach to treatment. The exact role of chemotherapy in treatment protocols is still unclear. The role of elective neck dissection is unclear.

Nitric oxide improves cisplatin cytotoxicity in head and neck squamous cell carcinoma.

OBJECTIVE: To test whether nitric oxide (NO) enhances the cytotoxicity of cisplatin in a head and neck squamous cell carcinoma (HNSCC) cell line. BACKGROUND: Cisplatin is one of the most frequently used chemotherapeutic agents in the treatment of HNSCC. NO has been shown to play an important role in regulating tumor growth. Previous studies demonstrate that NO can enhance the cytotoxicity of cisplatin in Chinese hamster lung fibroblasts. In this report, we examined the in vitro interaction of NO and cisplatin in a HNSCC cell line. MATERIALS AND METHODS: CCL23 cells were pretreated with three different NO donors: PAPA/NO (t 1/2 = 15 min), DPTA/NO (t 1/2 = 3 h), and DETA/NO (t 1/2 = 20 h). The cells were rinsed and exposed for 6 hours to a culture medium containing cisplatin. Cell survival and LD50 of cisplatin were calculated with and without NO pretreatment. RESULTS: PAPA/NO and DPTA/NO did not show any cytotoxic activity and did not change the LD50 of cisplatin. DETA/NO when used alone resulted in 25.6% cell death at its peak dose (100 microM). Pretreatment with DETA/NO resulted in almost a threefold reduction of the LD50 of cisplatin (6.8 vs. 2.4 microg/mL). Pretreatment with DETA/NO sensitized the HNSCC cells to subsequent cisplatin activity (two-sided P =.00016). CONCLUSION: Pretreatment of HNSCC cells with long-acting NO donors enhances cisplatin activity. Short- and medium-acting NO donors do not exert a toxic effect and do not augment the activity of cisplatin. NO agonists should be considered in the future as a possible adjunct to cisplatin in the treatment of HNSCC. Further studies with animal models are necessary to further clarify this relationship.

Gamma-probe localization of a parathyroid adenoma in the reoperative neck.

Preoperative localization of parathyroid adenomas in patients with hyperparathyroidism currently relies on a combination of computed tomography, magnetic resonance imaging, ultrasound, (99m)Tc-sestamibi scintigraphy, and venous sampling of parathyroid hormone. No procedure is universally reliable, however, and in reoperation for missed parathyroid adenomas, development of an optimal preoperative localization strategy becomes especially problematic. We report the case of a patient with hyperparathyroidism who required reoperation for a missed parathyroid adenoma despite preoperative localization with (99m)Tc-sestamibi scintigraphy. (99m)Tc-sestamibi scintigraphy was done 2.5 hours before reoperation. On reoperation, a gamma-detecting probe (C-Track; Care Wise Medical Corporation, Morgan Hill, CA) introduced through a right neck incision was used to localize a 4-cm adenoma within 45 minutes. No significant radiation hazard existed, and no special handling of the specimen was required. The patient's hyperparathyroidism resolved within 24 hours postoperatively. Therefore, this intraoperative technique may prove to be a useful adjunct to preoperative localization studies of parathyroid adenomas, particularly in patients requiring reoperation for persistent postsurgical hyperparathyroidism.

Extranasopharyngeal angiofibroma.

Juvenile nasopharyngeal angiofibromas are vascular neoplasms, which originate characteristically in the posterior lateral wall of the nasopharynx. Although angiofibromas extend beyond the nasopharynx commonly, they rarely originate outside the nasopharynx. Reports of primary extranasopharyngeal angiofibromas have appeared sporadically in the literature. We present an unusual case of an angiofibroma arising from the middle turbinate. The clinical characteristics of extranasopharyngeal angiofibromas do not conform to that of nasopharyngeal angiofibromas. Therefore, they can present diagnostic challenges. A methodic evaluation and a high index of suspicion are essential in establishing the proper diagnosis and treatment.

Carcinoma of the buccal mucosa.

OBJECTIVE: The goal was to analyze the outcome of surgical therapy for buccal carcinoma. STUDY DESIGN: A retrospective chart review was done. SETTING: The study took place in a major tertiary-care hospital. RESULTS: Twenty-seven patients received first-time surgical therapy for buccal carcinoma. Treatment was surgery alone in 15 and surgery followed by radiation therapy in 6 patients. Six additional patients received surgical salvage for radiation therapy failure. Composite resection of the tumor was performed in 16 patients (59%). Five-year observed actuarial survival rates were 100%, 45%, 67%, and 78%, and locoregional recurrence rates were 0%, 27%, 44%, and 0% for stages I to IV, respectively. The 5-year actuarial survival rates were 80% after surgery and 82% after surgery and postoperative radiation therapy. Patients who underwent surgical salvage after radiation therapy failure had a 1-year survival rate of 0%. CONCLUSION: Aggressive surgical treatment of buccal carcinoma may result in better survival rates. SIGNIFICANCE: The article analyzes buccal carcinoma in regards to the patterns of presentation, treatments rendered, and patterns of failure.

Combined radiotherapy with planned neck dissection for small head and neck cancers with advanced cervical metastases.

BACKGROUND: We have previously described our treatment algorithm for patients with small head and neck cancers with advanced cervical metastases (stage N2 or greater). Primary radiotherapy is given to the primary site and neck, followed 6 weeks later with endoscopy and biopsy of the primary site. If biopsy of the primary site is negative by frozen section, an immediate neck dissection is performed even when no clinical residual neck disease is present. Our initial review found that 36% of patients with a complete clinical response to radiotherapy had positive nodes on histological examination. STUDY DESIGN: Retrospective. METHODS: The medical records of 71 patients treated at UCLA Medical Center from 1986 to 1999 by this algorithm were reviewed. RESULTS: After radiotherapy, 69 of 71 patients had a complete response at their primary site. Forty-two patients had a complete clinical response in the neck. Seventy-one neck dissections were performed. Overall, 31 of 71 neck dissections (44%) had positive nodes. Among the 42 patients with a complete response to radiotherapy, 13 (31%) had positive histological nodes. Among the 29 patients with a partial response to radiotherapy, 17 (59%) had positive nodes. Follow-up and incidence of neck recurrence are discussed. CONCLUSION: Planned neck dissection for advanced cervical metastases remains controversial for patients with a complete clinical response to radiotherapy. However, our results suggest that clinical assessment after radiotherapy cannot assure the absence of neck disease. Until there are reliable methods to distinguish which patients are truly free of neck disease, we believe the benefits of a planned neck dissection outweigh the low morbidity of this procedure.

Surgical management of carotid body tumors.

OBJECTIVE: The goal was to review our experience in the management of carotid body tumors at a tertiary referral center. METHODS: A retrospective review was performed of patients at University of California-Los Angeles Medical Center in whom carotid body tumor was diagnosed between 1973 and 1998. RESULTS: Twenty-nine patients with 36 carotid body tumors were identified. Thirty-five operations were performed. Seventeen patients underwent preoperative embolization. The blood loss for these patients was less than for those without embolization. Five patients had preoperative cranial nerve deficits. Neurologic deficits were noted in 41% of patients immediately after surgery. In 24% of patients, the deficits were permanent. CONCLUSION: Surgical resection is the treatment of choice for carotid body tumors. Embolization immediately before surgery decreases blood loss and facilitates tumor removal. In our series, the risk of new postsurgical cranial nerve deficits was small. Observation of these tumors is not recommended because progressive growth is associated with increased risk of neurologic deficits.

Hemangiopericytoma of the head and neck.

PURPOSE: To report a series of patients with hemangiopericytoma (HP) of the head and neck, to review pathological features of these tumors, and to discuss management options. MATERIALS AND METHODS: A retrospective review of the medical records at the University of California, Los Angeles (UCLA) Medical Center in Los Angeles, CA, was done in order to identify those patients with primary HP of the head and neck, including soft tissue and mucosal sites. RESULTS: Ten patients with HP of the head and neck were identified. There was an equal sex distribution and an average age of 36 (range 10-65). Seven of the tumors arose from soft tissue sites in the head and neck, and the remaining 3 arose from the mucosa. All patients underwent wide excision of the primary lesion with a local recurrence rate of 40%. Thirty percent of patients developed metastatic lung disease 0 to 8 years after initial diagnosis. Each patient who developed metastatic disease had abundant mitoses on pathological review compared with rare or absent mitoses in the lesions that took a more benign course. CONCLUSIONS: Pathological appearance of resected HP is predictive of later metastatic potential. Long-term follow-up is necessary in patients even after radical resection because recurrence or metastasis may be delayed by many years.

Combined cisplatinum and laser thermal therapy for palliation of recurrent head and neck tumors.

In recent years endoscopically controlled laser-induced thermal therapy (LITT) has been increasingly accepted as a minimally invasive method for palliation of advanced or recurrent head and neck or gastrointestinal cancer. Previous studies have shown that adjuvant chemotherapy can potentiate endoscopic laser thermal ablation of obstructing tumors leading to improved palliation in advanced cancer patients. Eight patients with recurrent head and neck tumors volunteered to enroll as part of an ongoing phase II LITT clinical trial, and also elected to be treated with systemic chemotherapy (cisplatin, 80 mg/m(2)) followed 24 h later by palliative laser thermal ablation. Laser treatments were repeated in patients with residual disease or recurrence for a total of 27 LITT sessions. Four of the 8 patients treated with laser thermal chemotherapy remained alive after a median follow-up of 12 months. Of the 12 tumor sites treated, complete responses were located in the oral cavity (3), oropharynx (1), hypopharynx (1), maxillary sinus (1), and median survival for these patients was 9.5 months. This initial experience with cisplatinum-based laser chemotherapy indicates both safety and therapeutic potential for palliation of advanced head and neck cancer but this must be confirmed by longer follow-up in a larger cohort of patients.

Unintentional parathyroidectomy during thyroidectomy.

OBJECTIVES: In the United States thyroidectomy is a frequently performed surgery by both general and head and neck surgeons. Even the most experienced thyroid surgeon, however, has probably received a pathology report stating that an incidental parathyroid gland or parathyroid tissue was found in the submitted thyroidectomy specimen. The aim of this report is to explore some of the pathologic and clinical characteristics of unintentional parathyroidectomy during thyroidectomy. STUDY DESIGN: A retrospective review was performed of thyroidectomies performed at the University of California, Los Angeles, Center for the Health Sciences between 1989 and June 1998 which had pathology reports showing parathyroid tissue contained within the thyroidectomy specimen. This excluded any tissue submitted separately to be evaluated for parathyroid tissue and parathyroid tissue removed unintentionally during a thyroidectomy for a different procedure such as a laryngectomy or surgery for parathyroid disease. METHODS: The pathology slides were reviewed to determine the incidence of unintentional parathyroid tissue removal, the size of the parathyroid tissue found within the thyroid specimen, the location of the parathyroid tissue (extracapsular, intracapsular, intrathyroidal), and whether this unintentional parathyroidectomy during thyroidectomy caused clinical consequences. RESULTS: Four hundred fourteen applicable thyroidectomies were performed during this time with 45 (11%) discovered cases of unintentional parathyroidectomy during thyroidectomy. Twenty-five (56%) cases were discovered during thyroidectomy for benign disease, and 20 (44%) during thyroidectomy for malignant thyroid disease. All the parathyroid tissue was normal and was found in extracapsular (58%), intracapsular (20%), or intrathyroidal (22%) locations. Of these 45 cases, recurrent laryngeal nerve paralysis was found only in two patients who had the nerve resected intentionally during the thyroidectomy, and none of the patients developed permanent hypocalcemia. CONCLUSIONS: Incidental parathyroid gland tissue was reported in 11% of the thyroidectomies performed in our series, without the clinical consequence of hypocalcemia. The majority (78%) of this parathyroid tissue was found in the extracapsular and intracapsular locations; therefore it is possible that these parathyroid glands may be identified and preserved with more meticulous inspection of the thyroid capsule during and after thyroidectomy to decrease the incidence of unintentional parathyroidectomy during thyroidectomy in the future.

Clinical application of fluorescence in situ hybridization for chromosome 11q13 analysis in head and neck cancer.

OBJECTIVE: Squamous cell carcinoma of the head and neck (HNSCC) still has one of the lowest 5-year survival rates. Despite advances in diagnosis, treatment, and research, survival rates have not improved in recent years. This report examines the utility of fluorescence in situ hybridization (FISH) in detecting chromosome 11q13 amplification in HNSCC and in evaluating the correlation between 11q13 amplification and tumor behavior. STUDY DESIGN: This study used FISH to determine the incidence of 11q13 amplification in 20 HNSCCs and 10 normal controls from the same patients. Tumor touch preparations and paraffin-embedded tissues from the same patient samples were used for comparative analysis. Both single and dual color FISH was performed. METHODS: Repetitive chromosome 11 specific alpha satellite DNA probe and chromosome 11q13 specific probe cyclin D1 were used for the FISH analysis. RESULTS: Experiments revealed amplification of chromosome 11q13 in three fresh touch preparations. FISH on paraffin tissues showed amplification in two additional samples. Intensity of amplification, as high as 20 copies per nucleus, was observed in paraffin preparations, whereas a maximum of only six copies was seen in fresh preparations. Amplification was not detected in any of the normal samples. All five cases with 11q13 amplification had metastases and four of these were from poorly differentiated tumors. In the nonamplified cases, 5 of 15 had metastases and 2 of 15 was poorly differentiated. CONCLUSIONS: The present study indicates that FISH is a useful technique for detecting molecular changes such as amplification of chromosome 11q13 in HNSCC. FISH in paraffin preparations allows for accurate measurement of intensity of amplification and makes it possible for the evaluation of a large collection of archival material. The data also suggest that 11q13 amplification is correlated with poorly differentiated tumors and metastasis. Thus FISH has the potential to be a valuable diagnostic/prognostic tool in head and neck cancers.

Glandular carcinoma of the larynx: the UCLA experience.

Glandular carcinomas of the larynx are rare tumors that constitute less than 1% of all laryngeal malignancies. A retrospective case review of 12 patients with glandular carcinomas of the larynx is presented to identify patient and tumor characteristics, therapeutic modalities, and treatment outcomes. Ten patients underwent surgical excision of the primary tumor, by either supraglottic laryngectomy, vertical partial laryngectomy, or total laryngectomy. Seven of these patients also received postoperative radiotherapy. After a median follow-up period of 23 months, 7 of the 12 patients (58.3%) died as a result of uncontrolled locoregional disease or distant metastases. The 5-year survival rate was 57% in patients who underwent combination therapy versus 50% for those patients who received surgery alone. Surgical resection is the primary treatment modality used in the majority of cases. Neck dissection is reserved for patients with clinically apparent adenopathy, adenocarcinoma, or high-grade mucoepidermoid carcinoma. Combination therapy with surgical resection and radiotherapy may be more effective in achieving tumor remission than is surgical resection alone.

Radiotherapy followed by neck dissection for small head and neck cancers with advanced cervical metastases.

Patients with small or occult primary carcinomas of the head and neck with advanced cervical metastases present a difficult problem for the otolaryngologist. A retrospective review was performed of patients who presented to UCLA Medical Center between January 1986 and June 1996 with small or occult primary tumors of the head and neck with advanced cervical metastases. The treatment algorithm consisted of initial radiotherapy to the primary site and the neck, followed in 6 to 8 weeks with endoscopy and biopsy of the primary tumor site. As long as the repeat biopsy of the primary tumor site was negative by frozen section, an immediate neck dissection was performed, even if no residual neck disease was present. Almost 40% of patients with no clinical evidence of neck disease following radiotherapy had evidence of metastatic cancer on histopathologic examination. While some would consider a watchful waiting policy when there is no clinically detectable neck disease following radiotherapy, we believe it is preferable to perform immediate surgery in such patients, in light of the high incidence of microscopic metastatic disease.

Testicular carcinoma metastatic to the neck.

PURPOSE: To show that a supraclavicular neck mass may be indicative of metastatic testicular carcinoma and to offer further insight into the treatment of residual neck disease. METHOD: We report six cases of testicular carcinoma metastatic to the neck. All were initially treated with radiation, chemotherapy, or a combination of both depending on histological type. RESULTS: Neck masses persisted despite primary therapy. Three patients underwent subsequent modified neck dissection and remained free of disease; three others received nonsurgical forms of adjuvant therapy and ultimately died of their cancer. CONCLUSION: Metastatic testicular carcinoma may manifest as a supraclavicular neck mass and must therefore be considered in the differential diagnosis of a mass in this region. Surgical resection is indicated in the management of neck masses that persist after cytoreductive chemotherapy to remove residual foci of disease and potential source of spread.

Traumatic neuromas of the head and neck.

An interesting case of a traumatic neuroma of the greater auricular nerve provides the impetus for a discussion of head and neck neuromas. Traumatic neuromas of the head and neck are relatively rare. Division of the greater auricular nerve during parotidectomy occasionally results in a traumatic neuroma. We report a case of a 73-year-old woman who presented with a traumatic neuroma nine years after undergoing superficial parotidectomy with dissection of the facial nerve for a mixed tumor. The patient had a 1.5 cm x 1.0 cm mass located below the old surgical site over the anteromedial border of the sternocleidomastoid muscle. The patient's past history was significant for Frey's syndrome, which is the result of abnormal neurologic growth. On first impression, the tumor was thought to be a recurrence of neoplastic disease; however, because of the evaluation, traumatic neuroma was suspected. An attempt at fine-needle aspiration of the mass was too painful to be carried out. At surgery, a whitish tumor was excised which, on final pathologic examination, revealed traumatic neuroma. The surgical literature is reviewed and the subject of head and neck neuromas, including their evaluation and management, is thoroughly discussed. Knowledge of this possible diagnosis may spare the patient and the surgeon needless worry, as well as unnecessary procedures, once tumor recurrence has been ruled out.
